BOBBIN-HOLDER FOR SPINDLES SPECIFICATION forming part of Letters PatentNo. 538,501, dated April 30, 1895.

Application filed February 28,1895- Serial No. 539,999. (No model.)

To all whom it may concern: I

Be it known that I, OLIVER O. BURR, a citizen of the United States ofAmerica, residing at Westvale, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inBobbin- Holders for Spindles; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertaius to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The object of this invention is to provide a spindle with means forholding the bobbin in frictional contact therewith; and it consists inproviding the spindle with a cork sleeve which is secured in place byindependent wire coils of less external diameter than the cork sleeve,the coils serving the double purpose of holding the cork sleeve inposition and preventing its rotation upon the spindle, as will behereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation showing the'bobbin in place upon the spindle.-Fig. 2 is a side elevation showing the bobbin in section;-and Fig. 3 isa detail view with the parts separated upon the spindle, the cork sleevebeingin section.

In this class of invention numerous attempts have been made to provide acheap, simple and effective means for holding the bobbin inproperposition upon the spindle, and metallic sleeves, rubber tubes andyarn packings have been suggested, but in practice these devices havetheir objections, the metal springs being liable to slip on the smoothsurface of the spindle and be retained in the bobbin. They also cut andwear the bobbin. The rubber sleeves are objectionable in that they aredestroyed by contact with the oil and they are also liable to becomeheated and adhere to the bobbin. The wrapping of yarn upon the spindleis a makeshift usually employed and great loss of time ensues from itsuse as itinvariably pulls 0d the spindle with the bobbin.

The objections incident to the devices hereinbefore described are fullyovercome by my improvement hereinafter described.

A designates a spindle of the construction usually employed in spinningmachines, and B the bobbin which is of the well known type.

O designates a cork sleeve or tubular cork section and c and c designatecoils of wire, the diameter of the wires being less than the thicknessof the cork sleeve. These coils have normally an internal diameterconsid- 6o erably less than the diameter of the spindle to which theyare applied, and the ends of the cork sleeve are beveled inwardly sothat the coils will lie partially within the sleeve.

In applying my invention to a spindle one of the wire coils is firstplaced over the end of the spindle and driven down to the properposition thereon so as to firmly embrace said spindle. The cork sleeve 0is then placed over the end of the spindle and pressed down upon thecoil thereon, after which the other coil is driven down in contact withthe cork sleeve. The cork sleeve is of such size that it will properlyfit the bobbin, but should the diameter of the same be diminished it canbe slightly expanded by driving the upper coil down.

It will be noted that as the coils are originally of the same diameterthe upperone can be more readily removed, and should the cork 8o sleevebecome destroyed it can be readily replaced.

The device can be quickly made and is cheap in construction andefficient in use. Cork appears to possess certain qualities 8 5 whichrender it desirable for this use, it being elastic and not affected byoil, or moisture, or heat.

Having thus described my invention, what I claim as new, and desire tosecure by Letters ing expansible coilscand c and an interposed Intestimony whereof I atfix my signature cork sleeve with inwardly-beveledends, the in presence of two witnesses.
